Technical background
Tealeaves with its producing refreshing effect to the mind of having, cardiac stimulant diuresis, heat-clearing and fire-reducing, promote the production of body fluid to quench thirst, digest easypro stomach, detoxicating, killing bacteria, step-down effect such as make eye bright, went through more than 3000 year and flourishing long time.Modern study proves that further tealeaves also has preventing decayed tooth deodorizing, anti-cancer, radioresistance, anti-coronary heart disease etc. and regulates bodily fuctions and health-care effect.Be accompanied by human life style's the continuous change and the continuous quickening of rhythm of life, instant tea appears in the forties in 20th century, and tea beverage grows up.The seventies, tea beverage is always with the fast speeds development, and it is considered to a big class most possible and that soda contends with, is a representative of new age beverages.As a kind of natural health beverage, it has catered to modern consumer fully and has advocated natural, as to pay attention to health demand on the one hand; On the other hand, tea beverage is conveniently drunk characteristics, meets the requirement of modern way of life.In a word, quench one's thirst, drink well, healthy, fashion is the main cause that tea beverage attracts the consumer, tea beverage has bright development prospect as healthy food.
Cider contains nutritions such as natural vitamin, protein, iron, calcium, potassium, zinc, carbohydrate, can improve immunity, and softening blood vessel reduces cholesterol, and stabilizing blood pressure is regulated the human acid-base balance, improves facial nutrition, prevents skin aging.
An important directions of tea beverage development is a diversification of varieties.In the middle of tea beverage, fruit juice tea is an important kind, and it is to add modulation such as entry, original fruit juice (or inspissated juice), liquid glucose, acid to form in millet paste.Tea and fruit juice all are natural health beverage, and is nutritious, two kinds of healthy beverage combinations among the strong ones, and the advantage addition has better nutrition, health care.Fruit juice can improve the bitter taste of tea simultaneously, distinguishes the flavor of for tea with natural fruital, is subjected to consumer's welcome more.Seasoning tea beverage development at present is very fast, mainly is that fruit juice and tea beverage two big beverages all account for suitable market share, seasoning fruit juice tea market field promise well because filled up the space that fruit juice and fruit drink slower development stay.
Summary of the invention
In recent years, be accompanied by the raising of China's living standards of the people and the continuous improvement of quality of life, natural, healthy beverage more and more is subjected to consumer's favor.Tea beverage with its distinctive health care, has developed rapidly in the whole world since being born the seventies in 20th century.China's production of tea drinks is from the middle and later periods nineties, with average annual 200%~300% growth development, in various types of beverages is produced, is positioned at after water and the soda always, is sure to occupy the 3rd for many years; The original fruit juice beverage presented strong growth in nearly 2 years, was only second to tea beverage at present in various types of beverages is produced and occupied the 4th.
The purpose of apple oolong tea development is to adopt the microwave New Machining Technology, the trophic function of apple fumet and oolong tea is compound, when keeping good former tea and former cider local flavor, produce the apple oolong tea beverage that has both advantages concurrently, develop novel natural function health-care fruit juice tea beverage, the demand that adapts to the tea beverage diversification of varieties satisfies consumers in general's needs.
The present invention mixes with oolong tea with cider and is made into the apple oolong tea beverage, and by volume percentage meter cider is 20%-40%, and surplus is an oolong tea.
1), the preparation of apple fumet:
Apple is cleaned up, in the micro-wave oven of 640W, goes out enzyme after 3 minutes, peeling, stoning, squeeze the juice, filter, in filtered juice, add the vitamin C of 0.08%-0.12%, apple fumet.
2), the microwave abstracting of oolong tea:
Add deionized water in tealeaves, the ratio by weight/volume of tealeaves and deionized water is 1: 60-100, and the microwave power of employing 360~600w, extraction 4~8min removes tea grounds through coarse filtration, and sand core funnel is smart to be filtered, and gets the former oolong tea of the good oolong tea local flavor of tool.
3), the processing of apple oolong tea:
With apple fumet by volume percentage count 20%~40% and mix with 60%-80% oolong tea, regulating pol with xylitol is 4.0~7.0 ° of Bx, use 4200r/min, supernatant is got in the 15min centrifugation, add 0.05% beta-schardinger dextrin-, bottling is in 600W microwave disinfection 2min, capping, cooling is the apple oolong tea beverage.
Technological merit
1), the present invention adopts microwave to the apple preliminary treatment, kills the brown stain that polyphenol oxidase in the apple prevents apple, makes the apple fumet that squeezes can keep original juice look of apple and local flavor, no brown stain.
2), the present invention adopts the microwave abstracting oolong tea.Microwave abstracting have the extraction time short, extraction efficiency is high, can well keep the original color, smell and taste of oolong tea, inclusion is abundant, can keep the characteristics of its functional component better, flavour is good to eat, and is sour-sweet moderate, the band tea flavour, sensory evaluation scores reaches 96 fens; Physico-chemical analysis is the result show, every physical and chemical index of product is the standard of People's Republic of China's light industry standard: QB2499-2000 " tea beverage " head and shoulders above all, juice content>30% (v/v).

3), the present invention adopts microwave disinfection, it has fast, easy to operate, the advantage of energy savings, its existing fuel factor also has non-thermal effect, can be under lower temperature killing microorganisms, so both can keep original local flavor of tea beverage and nutriment well, kill harmful microorganism has effectively guaranteed the distinctive quality and flavor of product again.
4), pass through the apple oolong tea of the composite development of this technology: the soup look light yellow is green, and sour-sweet moderate, flavour is good to eat, the band tea flavour.Cider and oolong tea are composite, have enriched the flavour and the local flavor of oolong tea, and the Iron Guanyin of fragrance is accompanied by light apple perfume (or spice), has reduced the bitter taste of Iron Guanyin, makes the Iron Guanyin taste more mellow.And in allocation process, added functional xylitol, it does not participate in insulin metabolism, is fit to diabetes patient, also can not cause carious tooth, can improve intestinal microbiota system and the generation of prevention colon cancer, chemical property is stable, heat-resisting acidproof, increased its health care function; And heat of solution is big, gives refrigerant sweet taste, is suitable for the beverage seasoning.
6, embodiment
Choose Fuji apple of uniform size, the about 200g of weight.An apple is cleaned up at every turn and put into micro-wave oven, with the power of 640w, handle the 3min enzyme that goes out, peeling, stoning then, squeeze the juice, filter, 0.08%~0.12% the vitamin C that adds apple weight protects look to cider.
The production of oolong tea
Take by weighing 2.5g Iron Guanyin tealeaves, add the deionized water of 200ml.Microwave abstracting power is 600w, and processing time 5min removes tea grounds through the filter cloth coarse filtration, and the smart filter of sand core funnel gets oolong tea.
The preparation of apple tea
20%, 30%, 40% ratio that the cider for preparing and oolong tea juice accounted for according to apple water is mixed with oolong tea, uses 4200r/min, and supernatant is got in the 15min centrifugation, adds 0.05% beta-schardinger dextrin-.Bottling, and microwave disinfection (600w, 2min), capping, cooling gets the apple tea beverage.
